Hello I'm trying to use the function get_rectangles to return a list of
rectangles however I can' get the code to compile.
code
#include
std::vector< boost::polygon::rectangle_data<int> > rects;
typedef boost::polygon::polygon_90_with_holes_data<int> Polygon90;
Polygon90 poly;
typedef boost::polygon::polygon_traits<Polygon90>::point_type MyPoint;
MyPoint pts[] = { boost::polygon::construct<MyPoint>(0, 0),
boost::polygon::construct<MyPoint>(0, 10),
boost::polygon::construct<MyPoint>(30, 10),
boost::polygon::construct<MyPoint>(30, 20),
boost::polygon::construct<MyPoint>(10, 20),
boost::polygon::construct<MyPoint>(10, 0) };
boost::polygon::set_points(poly, pts, pts + 6);
boost::polygon::get_rectangles(rects, poly );
which gives the error
1>c:\lib\boost\1.57.0\boost\polygon\detail/rectangle_formation.hpp(261):

I'm quite new to both boost and templates so any help would be appreciated.
